Abstract

The invention discloses a mechanical molecular spring vibration isolation buffer device. In a mechanical molecular spring vibration isolation buffer technology, water is used as a force transferring medium, and pistons and pre-compressed springs are used as force bearing components; a vibration isolation buffer designed on the basis of the mechanical molecular spring vibration isolation buffer technology mainly comprises a main piston, a plurality of secondary pistons, a cylinder body and an upper end cover; the main piston is used for carrying the mass; each secondary piston is connected with a pre-compressed spring with specific rigidity; the cylinder body is filled up with water. The mechanical molecular spring vibration isolation buffer has distinct piecewise linear rigidity, comprises a bearing section, a working section and a limiting section, can achieve high-static and low-dynamic rigidity characteristics, has the characteristics of low working pressure intensity, adjustable performance parameters and the like, and is especially applicable to the low-frequency overloading field.

Description

technical field [0001] The invention belongs to the technical field of vibration isolation and buffering devices, and in particular relates to a mechanical molecular spring vibration isolation and buffering device. Background technique [0002] Vibration is always one of the focal issues in the fields of aeronautics, aerospace, marine and vehicle engineering. Generally speaking, vibration will lead to structural fatigue damage, reduce the performance of instrumentation equipment, and reduce ride comfort. In the field of national defense, strong vibration will affect the survivability and combat technical performance of weapons and equipment. Passive vibration isolation technology is widely used because of its simplicity, low price, and reliability, such as metal spring isolators, metal rubber isolators, rubber isolators, wire rope isolators, air spring isolators, etc. However, the vibration isolation effect of these vibration isolators in the heavy-load and low-frequency f...
